This gives it an appearance that is similar to a spider’s web, with a central axis that possesses at least three spokes, called radii, extending from it. Radar charts depict multivariate data of three or more quantitative variables mapped onto an axis. This makes it a suitable graph to measure multivariate data being shared among similar groups, individuals, or objects. They are also used for ordinal measurements, where each variable corresponds to ‘better’ in some aspect, and all variables on the same scale. Each variable value is plotted along its individual axis and the variables are connected together to form a polygon shape.Ī radar chart’s primary function is to clearly show commonality and outliers. This forms what resembles a spider’s web. All axes are arranged radially with equal distances between each other and connecting grid lines. Within a radar chart, each variable is provided with an axis that starts from the center. Because of this, they are commonly used to analyze performance data in professional sports, like charting a player’s relative strengths and weaknesses. This also makes them particularly good for identifying any outliers amongst each variable. Radar charts can be used to show multiple quantitative variables and are an awesome way of showing or highlighting which parts of the data stands out in comparison to the rest. Visualizing that data by turning it into a radar chart, makes it easier for your audience to understand. It can be difficult for viewers to interpret large tables with a lot of data and cells. They are also occasionally called a spider graph, polar chart, web chart or star plot. Radar charts are effectively a line or area chart, wrapped around a central axis. A radar chart can be an intriguing way of presenting your data.
